Sorry to dig this one up, but this question was obviously misunderstood and remains unanswered. I'd just be asking the exact same question.
Does anyone know a way to use 'flat' or instanced geometry with hair, and have it pick up the color of the object it's attached to?
i.e the color of the flat polygons should be a solid color, defined by the color of the parent object's UV map at the point where it's attached. Exactly as it works with generate set to none
We don't won't ' individual but identical UV mapping.' . that's exactly what we don't want.
